Following the previous "Juniper Old Driver Experience" (SRX Firewall optimization), Juniper old driver experience (SRX firewall NAT and strategy) The second video course was recorded on the line.1, two courses are completely independent and combined,SRX Firewall Optimization Chapter is for firewall dual-machine, configuration optimization content.The

Juniper Old driver Experience (SRX Firewall optimization) Video course on lineEveryone in the QQ group, the forum often ask questions, many people on the SRX double machine is not very understanding, the actual work encountered too many problems, provoked a little trouble.For this I recorded a Juniper old driver experience (SRX Firewall optimization) Video course

SRX operating system software upgrades must follow these steps: 1. Management Terminal Connection SRX console port, facilitate the upgrade process to view the device restart and software loading status. 2. Open the FTP service on the SRX and upload the downloaded upgrade software media to the SRX via the FTP client u

Today, we will demonstrate how the Juniper SRX Firewall runs ipsec vpn + OSPF with Cisco routers.

R2 simulates a carrier device, C1 is a zhuyun device, and bridging with SRX, which is equivalent to a firewa

To configure the firewall HA, follow these steps:1. First, directly connect the HA control signal ports of the two firewalls. The HA control signal port is the port specified by the manufacturer.Device Model:For SRX100 devices, connect the fe-0/0/7 port to the Fe-1/0/7 portFor SRX210 devices, connect the fe-0/0/7 port to the Fe-2/0/7 portFor SRX240 devices, connect the ge-0/0/1 port to the ge-5/0/1 portFor SRX650 devices, connect the ge-0/0/1 port to the ge-9/0/1 port2. Configure the root passwo

Real juniper devices are expensive, so we use simulators to simulate juniper routers and juniper srx firewalls. The topology is simple: Juniper router em0.0 ------------ VM1----------------SRX ge0/0/0.0 That is to say, the first network adapter of juniper router and srx is connected to VM1, which is equivalent to a direct connection between juniper router and

Zhan Bo Juniper) SRX is relatively simple to establish a VPN site, and NAT is also simple to use. What I want to talk about is the joint application between them. Requirements: Local A and local B establish A VPN site connection, A remote place C through the leased line to the local, the remote only to the local A route, and cannot add A route. Remote C is required to access VPN Site B through local. Let's take a look at the configuration of the VPN s

As mentioned in the previous blog (simple C/S chat room), we have adopted the multi-thread method. The main thread on the server is responsible for continuously listening on the port, and the subthread is responsible for receiving and sending messages. The main thread of the client needs to receive keyboard messages and send them to the server. The subthread needs to receive messages sent from the server. In the implementation of this simple C/S
